2023年2月12日 · Percutaneous transluminal coronary angioplasty (PTCA), or percutaneous coronary intervention (PCI), is a minimally invasive procedure to open blocked or stenosed coronary arteries, allowing unobstructed blood flow to the myocardium. The blockages occur because of lipid-rich plaque within the arteries, diminishing blood flow to the myocardium.

经皮冠状动脉腔内成形术(ptca)是治疗冠状动脉粥样硬化性管腔狭窄最基本最主要的介入性技术。 经皮穿刺周围动脉将带球囊的导管送入冠状动脉到达狭窄节段，扩张球囊使狭窄管腔扩大，血流畅通。

国外随机对照研究表明 ,冠状动脉腔内成形术(PTCA)能明显减轻心绞痛和急性心肌梗塞症状和降低死亡率 ;而冠状动脉内支架术 (STENT术 )可明显减少PTCA术后急性血管闭塞和降低再狭窄率。

PTCA short for percutaneous transluminal coronary angioplasty is also called coronary angioplasty, balloon angioplasty or percutaneous coronary intervention (PCI), is a minimally invasive procedure to open up blocked coronary arteries, allowing blood to circulate unobstructed to the heart muscle 1.

2024年8月5日 · PTCA, or percutaneous transluminal coronary angioplasty, is a minimally invasive procedure that opens blocked coronary arteries to improve blood flow to the heart muscle. First, a local anesthesia numbs the groin area. Then, the doctor puts a needle into the femoral artery, the artery that runs down the leg.

Percutaneous transluminal angioplasty, stenting and atherectomy are minimally invasive (endovascular) procedures that restore blood flow when arteries are clogged due to peripheral artery disease. Stenting, in which a tube is placed in the artery to hold it open, is often part of the angioplasty procedure.

Stents. Coronary stents are now used in nearly all angioplasty procedures. A stent is a tiny, expandable metal mesh coil. It's put into the newly opened area of the artery to help keep the artery from narrowing or closing again. Tissue will start to coat the stent like a layer of skin once the stent has been placed.

PTCA is a nonsurgical procedure that relieves narrowing and obstruction of the arteries to the muscle of the heart (coronary arteries). This allows more blood and oxygen to be delivered to the heart muscle. PTCA is now referred to as percutaneous coronary intervention, or PCI, as this term includes the use of balloons, stents, and atherectomy ...

For Percutaneous Transluminal Coronary Angioplasty (PTCA), medical professionals perform a minimally invasive procedure to treat blocked or narrowed coronary arteries. Here's a step-by-step breakdown of what they do during a PTCA:

2024年1月9日 · PTCA is a procedure that involves using a small balloon to open up a blockage or narrowing inside an artery. A stent is a metal mesh tube that a doctor may insert during the procedure.
